I already have a momo steering wheel installed, but I now want the horn to work. Does anyone have any info on how to do this? I've found a bit, and I think I have the basic idea, but if someone could tell me which wire is for the horn, and if you have to do anything with a ground wire that would really help me. I can find this for other cars, but nothing for the wrx's. Just lots on how to do the actual wheel install, which I don't need.
Thanks in advance.
